在 2012 年，飓风袭击纽约的时候，当地的医院就曾经面临这种困境；而在这次疫情中，如今很多地方的医院也同样面临这种困境。有专家提倡按照纯粹的年龄和健康状况来筛选，谁最有可能存活时间就先拯救谁；也有人赞成单纯的抽签，不管怎样，大家一致认为肤色、身份、社会价值、民族背景等不应该影响到最终的决策。
事实上，在意大利的一些医院，因为 ICU 数量不够，很多医生正面临着这种生死抉择，而且当地的医疗组织也提供了一些选择建议：给接受重症监护治疗的病人设置年龄限制。「丁香园」的文章详细讨论了年龄限制是否合理，可以跟本文一起配合阅读。
丁香园：为转入 ICU 的患者设置年龄限制，这样公平吗？
The medical director of the intensive care unit had to choose which patients’ lives would be supported by ventilators and other equipment. Hurricane Sandy was bearing down on Bellevue Hospital in New York City in 2012, and the main generators were about to fail. Dr. Laura Evans would be left with only six power outlets for the unit’s 50 patients.
在某些情况下，重症监护室的医疗主管必须做出选择，决定哪些病人的生命可以得到呼吸机和其他设备的维持。2012 年，飓风「桑迪」袭击纽约市贝尔维尤医院，主发电机即将失灵。劳拉·埃文斯医生只剩下 6 个电源插座可用，而重症监护室内却有 50 名病人。
Hospital officials asked her to decide which ones would get the lifesaving resources. “Laura,” one official said, “we need a list.” After gathering other professionals, Evans checked off the names of the lucky few.
Now she and doctors at hospitals across the country may have to make similarly wrenching decisions about rationing on a far bigger scale. Epidemic experts predict an explosive growth in the number of critically ill patients, combined with severe shortages of equipment, supplies, staffing and hospital beds in areas of the U.S. where coronavirus infections are surging — hot spots that include New York, California and Washington state.
Health workers are urging efforts to suppress the outbreak and expand medical capacity so that rationing will be unnecessary. But if forced, they ask, how do they make the least terrible decision? How do they minimize deaths? Who even gets to decide, and how are their choices justified to the public?
Medical providers are considering these questions based on what first occurred in China, where many sick patients were initially turned away from hospitals, and now is unfolding in Italy, where overwhelmed doctors are withholding ventilators from older, sicker adults so they can go to younger, healthier patients.
Choosing between patients “goes against the way we used to think about our profession, against the way we think about our behavior with patients,” said Dr. Marco Metra, chief of cardiology at a hospital in one of Italy’s hardest-hit regions.
In the United States, some guidelines already exist for this grim task. In an effort little known even among doctors, federal grant programs helped hospitals, states and the Veterans Health Administration develop what are essentially rationing plans for a severe pandemic. Now those plans, some of which may be outdated, are being revisited for the coronavirus outbreak.
But little research has been done to see whether the strategies would save more lives or years of life compared with a random lottery to assign ventilators or critical care beds — an option some support to avoid bias against people with disabilities and others.
Some commonly recommended rationing strategies, researchers found, could paradoxically increase the number of deaths. And protocols involve value judgments as much as medical ones and have to take into account the public’s trust.
If hospitals withhold treatment by age, where do they draw the line? If they give lower priority to those with certain underlying health conditions, they may in effect be offering black Americans less treatment than white Americans. If physicians try to redirect resources — putting a patient on a ventilator for a few days, then giving it to someone else who appears to have better prospects — more people may die because few would get adequate treatment. And if many patients have a similar chance of survival, what fair way is there to make a choice?
The federal government — so far, at least — is not providing national rationing guidelines for the coronavirus outbreak. Officials from various states, medical associations and hospitals are discussing their own plans, potentially resulting in very different decisions on life-and-death matters about which there are deep disagreements, even among medical professionals.
“You have to be really clear about what you are trying to achieve,” said Christina Pagel, a British researcher who studied the problem during the 2009 H1N1 flu pandemic. “Maybe you end up saving more people, but at the end you have got a society at war with itself. Some people are going to be told they don’t matter enough.”
「你必须非常明确设法达成的目标是什么，」英国研究人员克里斯蒂娜·帕格尔说；她曾经研究过 2009 年 H1N1 流感大流行期间的配给问题。「可能到头来你拯救了更多的人，但最终会引起社会各界的纷争。一些人会得知，他们不够重要。」
‘The Most Good’
Just before the coronavirus outbreak, Evans, the physician at Bellevue, moved across the country to direct the intensive care unit at the University of Washington Medical Center in Seattle. The city became one of the first areas in the United States to see community spread of the virus.
The hospital is doing whatever it can to prevent the need to ration — what Evans referred to as “an ethical obligation.” Like other institutions, it is trying to increase supplies, training staff to act in roles that may be outside their usual jobs and postponing elective surgeries to free up space for coronavirus patients. Some cities are racing to construct new hospitals.
Strategies to avoid rationing during the pandemic were published by the National Academy of Medicine. But hospitals across the country vary in their adherence to such steps. At the University of Miami’s flagship hospital, surgeons were told last Monday to cancel elective surgeries, but across the street at Jackson Memorial Hospital, they were “given wide discretion over whether to cancel or proceed,” according to an update sent to physicians.
尽管美国国家医学科学院已经发布了疫情大流行期间避免使用配给制的策略，但全美医院在实际执行时却各有差异。3 月 9 日，迈阿密大学旗舰医院的医生接到通知，取消选择性手术；而马路对面的杰克逊纪念医院，医生收到的更新信息则是：「授予了较大的权限，可酌情决定是否取消或继续实施选择性手术。」
Evans is working with health leaders in Washington state to figure out how to implement triage plans. Their goal, she said, would be “doing the most good for the most people and being fair and equitable and transparent in the process.”
But guidance endorsed and distributed by the Washington State Health Department last week suggested that triage teams under crisis conditions should consider transferring patients out of the hospital or to palliative care if their baseline functioning was marked by “loss of reserves in energy, physical ability, cognition and general health.”
The concept of triage stems from Napoleon’s battlefields. The French military leader’s chief surgeon, Baron Dominique Jean Larrey, concluded that medics should attend to the most dangerously wounded first, without regard to rank or distinction. Later, doctors added other criteria to mass-casualty triage, including how likely someone was to survive treatment or how long it would take to care for them.
Protocols for rationing critical care and ventilators in a pandemic had their beginning during the anthrax mailings after the Sept. 11 attacks but have not previously been implemented.
疫情大流行期间的重症护理和呼吸机配给方案，始于 911 恐怖袭击后的炭疽邮件事件，但这些方案之前从未实施过。
Dr. Frederick Burkle, a former Vietnam War physician, laid out ideas for how to handle the victims of a large-scale bioterrorist event. After the SARS outbreak stressed Toronto hospitals in 2003, some of his ideas were proposed by Canadian doctors, and they made their way into many American plans after the H1N1 pandemic in 2009. “I have said to my wife, ‘I think I developed a monster here,’” Burkle said in an interview.
如何为大规模生物恐怖主义事件的受害者制定配给方案，前越南战争军医弗雷德里克·博克勒曾经解释过。2003 年非典爆发后，加拿大多伦多的医院压力陡增，那里的医生提议借鉴博克勒的想法；这些医生也在 2009 年 H1N1 流感大流行后参考了很多美国方案。「我已经跟妻子说了，『我认为自己在这里制造了一个怪物，』」博克勒在一次采访中称。
What worried him was that the protocols often had rigid exclusion criteria for ventilators or even hospital admission. Some used age as a cutoff or preexisting conditions like advanced cancer, kidney failure or severe neurological impairment. Burkle, though, had emphasized the importance of reassessing the level of resources sometimes on a daily or hourly basis in an effort to minimize the need to deny care.
Also, the plans might not achieve their goals of maximizing survival. For example, most called for reassigning a ventilator after several days if a patient was not improving, allowing it to be allocated to a different patient.
But rapidly cycling ventilators might not give anyone enough chance to improve. When the coronavirus causes severe pneumonia, doctors are finding that patients require treatment for weeks.
In Canada, a study of H1N1 patients found that 70% of those who would have been withdrawn from ventilators after a five-day time trial if a rationing plan had been implemented actually survived with continued care.
在加拿大，一项针对 H1N1 病人的研究发现，70% 的患者经过持续护理存活了下来；但如果实施了配给方案，在 5 天的尝试后撤下呼吸机，就不会有那么多幸存者了。
Researchers at a British hospital had similar findings, concluding that “a new model of triage needs to be developed.”
A Score Card and a Lottery
Many of the original plans in the U.S. were developed exclusively by medical personnel. But in Seattle, public health officials gathered community input on a possible plan more than a decade ago.
Some citizens feared that using predicted survival to determine access to resources — a common strategy — might be inherently discriminatory, according to a report on the exercise. Citing “institutional racism in the health care system,” they were concerned that the metrics for some groups, like African Americans and immigrants, would be skewed because they had not received the same quality of care.
There were similar findings in Maryland, where researchers at Johns Hopkins engaged residents across the state in deliberations over several years.
The researchers presented them with several options. Hospitals could assign ventilators on a first-come, first-served basis. Some thought that could disadvantage people who lived far from hospitals. A lottery struck other participants as more fair.
Others argued for a more outcome-oriented approach. One goal could be saving the highest number of lives, regardless of factors like age. A different goal could be saving the most years of life, a strategy favoring younger, healthier patients. Participants also considered whether those playing a valuable role in a pandemic, like medical workers who risked their lives, should be made a priority.
After the project ended, the Hopkins researchers designed a framework that assigns scores to patients based on estimated probability of short- and long-term survival. The latter was defined by whether the person had a pre-existing life expectancy of at least a year. Ventilators would be provided, as available, according to their ranking. The framework recommends a lottery for lifesaving resources when patients have identical scores. Stage of life may also be used as a “tiebreaker.” Decisions should be made by designated triage officers, not individual doctors caring for patients, and there should be a limited appeals process in cases of resource withdrawal, the protocol said.
The public input led the Hopkins researchers not to incorporate most exclusion criteria.
Dr. Lee Daugherty Biddison, one of the effort’s leaders, said that was because most participants were uncomfortable excluding patients with underlying health issues. Preconditions don’t always predict survival from respiratory viruses, and having chronic diseases like diabetes, kidney failure and high blood pressure often tracks with access to medical care. Rationing based on these conditions would be “essentially punishing people for their station in life,” Biddison said.
The Hopkins group published a description of the framework last year, and doctors from other Maryland hospitals are teleconferencing twice a day to prepare to implement the plan if conditions grow extreme. Biddison has also been sharing the recommendations with doctors across the country.
In Pennsylvania, Dr. Douglas White, chairman of ethics in critical care medicine at the University of Pittsburgh School of Medicine, is using the Hopkins protocol to help prepare hospitals in his state.
In Colorado, Dr. Matthew Wynia, a bioethicist and infectious disease doctor, is working on a plan that would also assign a score. In his rubric, the first considerations are odds of survival and expected length of treatment. He said there was wide agreement among planners “not to make decisions on perceived social worth, race, ethnic background and long-term disability status,” which some fear could happen if doctors had to make seat-of-the-pants judgments without guidelines.
He is also trying to ensure that patients on admission to Colorado hospitals are asked whether they would forgo a ventilator if there were not enough for everyone. “One thing everyone agrees on is that the most morally defensible way to decide would be to ask the patients,” Wynia said.
He supports the idea of reassigning ventilators in certain cases. “If things are clearly getting worse, it’s really hard to justify a stance of once you’re on a vent, you own it, no matter how many people have to die in the meantime,” Wynia said.
Unlike in Italy, where age has been used in rationing treatment, some people developing protocols elsewhere have de-emphasized it. “There are arguments about valuing the young over the old that I am personally very uncomfortable with,” Pagel, the British researcher, said, including that young people should be a higher priority because they have more life ahead of them.
“Where is your threshold? Is a 20-year-old really more valuable than a 50-year-old, or are 50-year-olds actually more useful for your economy because they have experience and skills that 20-year-olds don’t have?”
「你设定的门槛是什么？20 岁的年轻人真的比 50 岁的老人更有价值吗？还是说，50 岁实际上对你的经济更有用，因为他们已经积累了 20 岁所没有的经验和技能？」
A Right to Know
As Hurricane Sandy intensified outside Bellevue in 2012, Evans referred to New York state guidelines, since updated — which some hospital leaders have said they will follow if overwhelmed by the coronavirus — on how to allocate ventilators in a pandemic using a scoring system that tries to estimate someone’s chance of survival. She pulled together an ad hoc committee of doctors, ethicists and nurses. “Having a system and procedures gave us a sense we had some control of the situation,” she recalled.
For those about to lose electricity, she and her colleagues stationed two staff members at the bedside of all patients who relied on ventilators, preparing to manually squeeze oxygen into their lungs with flexible Ambu bags.
Looking back, Evans feels the patients and their families had the right to know that their machines would lose power, but in the crisis they hadn’t been told. The doctors also did not think to ask whether any patients or their families might volunteer to give up a power outlet so that it could be provided to someone else. “It wasn’t even on my radar,” Evans said.
In the end, it was improvisation that prevented tragic rationing at Bellevue. The generator fuel pumps failed, but a chain of volunteers hand-carried diesel up 13 flights of stairs. Evans’ patients were all maintained on backup power until they were transferred to other hospitals.
最终，团队临时想出的应对办法避免了在表维医院发生悲剧性的配给。发电机的燃油泵出现了故障，但一波又一波的志愿者手提柴油机，送上了 13 楼。埃文斯每一位病人的生命都靠备用电源得以维持，直到转移至其他医院。
“I remember it really vividly,” she said of the experience. “It’s going to stay with me my entire professional career.”
